摘要在爱荷华州市建立了一个原型气象站，用于测量地面气象参数，其精度和分辨率足以进行现代尺度和尺度分析。介绍了传感器的特点，并对七场风暴的降雨率时间序列进行了初步分析，得到了以下结果：（a）在短时间尺度上存在缩放，在大多数情况下，它延伸到几十秒，并且它不延伸到所有风暴的较长时间尺度，和（B）七个风暴中的四个风暴呈现双曲线的概率分布，在大多数情况下，相关指数的值接近2，但高于先前从雷达和常规雨量计数据获得的值。对一个特定的春季风暴的并发地面气象变量的时间序列的分析表明，时间序列的相互依赖性与隐含的减少…
Abstract A prototype meteorological station has been established in Iowa City for the measurement of surface meteorological parameters with accuracy and resolution sufficient to allow for modern dimensional and scaling analyses. The sensor characteristics are presented and an initial analysis of the rain-rate time series of seven storms with high quality data yielded the following results: (a) scaling exists for the short timescales, which in most cases extended up to a few tens of seconds, and it does not extend to the longer timescales for all the storms, and (b) four of the seven storms exhibit hyperbolic behavior of the exceedance probability distributions, with the value of the associated exponent in most cases being near 2 but higher than the values obtained previously from radar and conventional rain gauge data. Analysis of the time series of concurrent surface meteorological variables for a particular spring storm shows that there is interdependence of the time series with an implied reduction of ...
